This is a very nice looking deck.
Having this card Herald of Orange Light is great. But I would side it not main it.
The reason behind this is, you run x3 Herald of Perfection and this card is just stupid amazing
>> I would change the x2 Herald of Orange Light with x2 effect Veiler or even one more Kristya and Gellenduo>>
>>> I just feel that the deck would be more consistent without the Herald of Orange Light in the main deck.
All and all great looking deck and for this format you should have much success
